When the fourth official held up the number '8' with Vidal ready to enter the fray, Ernesto Valverde's decision was greeted with uproar by supporters in the Camp Nou.
Though surely more for the protagonist of the substitution than for the change itself, as Arthur was playing sensationally. The Camp Nou gave him a standing ovation as many stood up to say goodbye to him.
It happened in the 77th minute. Arthur returned the affection, raising his arms to the stands. Vidal entered in his place and was received by whistling from the crowd. The jeers soon turned to applause as Vidal intercepted two Inter passes.
The Chilean midfielder did not have a bad game as he came on, playing a vital part in Jordi Alba's late goal, though it seems that Arthur could be becoming a fan favourite in Barcelona.
